Unit 1 Ecosystem Flashcard

Front

What is cellular respiration?

Back

Cellular respiration is the process by which cells convert glucose and oxygen into energy (ATP), carbon dioxide, and water.

Front

Which gas is a byproduct of cellular respiration?

Back

Carbon dioxide is a byproduct of cellular respiration.

Front

What is the primary source of energy for plants during photosynthesis?

Back

The primary source of energy for plants during photosynthesis is solar energy.

Front

Describe the flow of energy in an ecosystem.

Back

Energy flows from producers to consumers to decomposers in an ecosystem.

Front

What is photosynthesis?

Back

Photosynthesis is the process by which green plants use sunlight to synthesize foods with the help of chlorophyll.

Front

How do trees obtain energy?

Back

Trees obtain energy by producing food through photosynthesis.

Front

What is the difference between energy flow and matter cycling in an ecosystem?

Back

Energy flows in one direction through an ecosystem, while matter is recycled and cycled.

Front

What role do decomposers play in an ecosystem?

Back

Decomposers break down dead organic matter, returning nutrients to the soil and completing the nutrient cycle.

Front

What is the role of producers in an ecosystem?

Back

Producers, such as plants, convert solar energy into chemical energy through photosynthesis.

Front

Define the term 'ecosystem'.

Back

An ecosystem is a community of living organisms interacting with their physical environment.
